摘要
针对目前信息系统开发中,需求分析经常遇到的难题,提出了一种基于UML的信息系统需求分析方法,给出了一个需求分析框架,通过活动图技术来对业务流程建模,用对象图模型、状态图模型、交互图模型来构造系统的领域模型.讨论了业务建模、用例的提取、用例的集成等关键技术的实施步骤,使该方法具有更强的可操作性.
Requirements analysis is an extreme important step of software development. Aimed at the difficulties of requirements analysis of IS(information system) nowdays, a framework of requirements analysis based on UML is presented. The technology of UML Activity Diagrams is used to model business workflow, UML Object Diagrams,UML State Diagrams and UML Object Interactive Diagrams is used to model domain model of system. At the same time, the implement process of the key technology(business model,use case extracted and use case integrated ) is discussed in detail and the method of maneuverability is enhanced.
